4 Claims.

My invention relates to an oil burner, more particularly to a burner for burning different types and grades of fuel oil and the objects of my invention are:

First, to provide an oil burner of this class which is adjustable throughout so that it is applicable for use in connection with burning various types or grades of fuel oils or fluids;

Second, to provide an oil burner of this class with a novel vaporizing means;

Third, to provide an oil burner of this class with novel air inlet damper means;

Fourth, to provide an oil burner of this class which is particularly arranged to be positioned in the ordinary lid opening of a wood or coal burning stove;

Fifth, to provide an oil burner of this class which may be easily taken apart for cleaning the same if desired; I

Sixth, to provide an oil burner of this class in which all of the parts and portions are relatively adjustable;

Seventh, to provide an oil burner of this class which is very simple and economical of construction, easy to operate, efiicient in its action and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Figure 1 is a top or plan view of my oil burner complete; Fig. 2 is a side elevational viewthereof and Fig. 3 is an enlarged sectional view taken from the line 3-3 of Fig. 1 showing some of the parts in elevation to facilitate the illustration.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings:

The supporting housing I, adjustment spider 2, fuel inlet conductor 3, air damper 4, vaporizing members 5, 6 and I, and housing 8 constitute the principal parts and portions of my oil burner.

The supporting housing I consists of a d sklike plate portion I a which is adapted to fit into a conventional stove lid opening, as shown by dash lines in Fig. 3 of the drawings. This plate I is provided with a large central opening Ib and between this central opening and the periphery is provided an upwardly extending annular housing portion Ic which is preferably integral therewith as shown best in Fig. 3 of the drawings.

Positioned on the upper edge of the portion Ic of the member I is an adjustment spider 2. This spider member 2 is provided with three extended finger members in the preferred form as shown best in Fig. 1, but may have more if desired. It is provided centrally with an upwardly extended hub portion 2a which is screw threaded at 2f to be screw-threaded on the threads 3a of the fuel inlet conductor 3, all as shown best in Fig. 3. This fuel inlet conductor 3 is a pipe-like tubular member provided with threads 3b at its upper end adapted to receive the threads of a conductor for the fuel oil from any supply, not shown. Screw-threaded on the thread 3a of the member 3 is the hub portion 4a of the air damper 4. This air damper 4 is a disk-like member which is adapted to rest over the opening lb in the member I and may be raised and lowered relatively thereto by means of the threads 4b in the hub portion 4a on the thread 3a of the member 3. This damper member 4 is provided with a plurality of air inlet openings 40 through which the air passes downwardly into and around the vaporizer consisting of the members 5, 6 and I.

The vaporizer member 5 is provided with an upwardly extending hub portion 5a which is screw-threaded with threads 5b which are adapted to fit the lower ends of threads 3a," it being noted that the thread 3a on the member 3 extends from the lower end to past the upper side of the hub 2a, as shown best in Fig. 3 of the drawings. This hub portion 5a is provided with lateral ports 50 which permit the fuel oil to pass outwardly as shown by arrows inFig. 3. The main portion 5d of the member 5 is a relatively thin disk-like member so that it heats quickly to provide quick vaporization to facilitate the lighting of the burner.

The periphery of the member 5d rests on a flange portion 6a of annular nut 6,: as shown best-in Fig.3. This .member. 6. is .provided 'with threads 6b which are screw-threaded on threads Ia on the lower edge of the annular member I which forms the side wall for the vaporizer consisting of the members 5, 6 and I. This member I extends upwardly some distance to near the lower side of the opening in the member I a. The blaze from the burner extends from near the upper inner side of the member 'I over the upper edge and outwardly as shown by arrows in Fig. 3. Inasmuch as the vaporizer consisting of the members 5, 6 and I is secured on the lower end of the member 3, it will be noted that by turning the adjustment spider 2 on the member 3, the vaporizer member may be raised and lowered and held in such raised or lowered position, also the damper member 4 may be raised and lowered relatively to the opening lb by turning the same on the member 3.

Secured to the lower side of the supporting housing I and extending around the vaporizer consisting of the members 5, 6 and l is the vaporizer housing 8which is provided with a substantially semi-spherical cup-shaped 7 member Be at its lower side which is integralrwith a disklike portion 81) which is provided with a relatively large central opening 80 in which the vaporizer member is centralized. This portion 8b is pro vided at its periphery with an upwardly extending flange portion 8d. This member 8 is supported by means of three upwardly extending lugs 8e.

which are secured to the member I by means of.

screws 8]. Thus the vaporizer housing 8 is rigidly secured in such relation with the supporting ho.using I;

The. operation of myoilhurner is substantially as follows: Fuel oil in regulated quantities passes down theinterior of, the inlet conductor 3;.and passes outwardly through the. openings 50 into'the vaporizer as shown by arrows inFig. 3. Air passes downwardly around the -me'mbeis,'ib, 2c and 2d into the member lcand through the openings 40 in the damper 4 contacting. the, fuel-oil vapor in the upper part of the vaporizer portion I forming mixed fuel in the upper portion of this vaporizer member I which is ignited between the members 8e by a match, or otherwise. Any par.- ticle of the fuel-oil not burned will go. into the cup shapedmember 8av and will be later burned and utilized. In order to properlyadjust the air flow and vaporizer position, the spider 2 may be. turned to raise the fuel inlet conductor 3 upwardly toward the air stream passing through the openlugs 40. At the same time the damper member 4 will be raised from its seat admitting. air all around the outside. Thisdamper member may be turned by placing a pointed instrument between the members 21), 2c r 2d and into one of the openings 40 and turning. the member 4 on the fuel inlet conductorv 3 while the vaporizing. member remains stationary, thus providing forthe burning of various gravity fuels and various quality fuel oil.

Though I have shown and describedaparticular. construction, combination and arrangement of parts and portions, I do not-wishto be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having. thus described. my invention, what'I claim as new and clesireto secure by.Letters Patent is:
